This week Judit Polgar participated in the UNAM Torneo Cuadrangular in Mexico, defeating Ivanchuk in the first round of the knockout format tournament, and advancing to face Topalov in a 4 game rapid showdown. Having taking years off from chess, with only a few appearances here and there, most people probably did not expect her to outperform the former world champion so easily, winning 3 games and drawing 1.
